Symfony debug toolbar doesn't show up, I tried to check a lot of things, but no luck so far.
I am running site on app_dev.php environment, my config_dev.yml has:
web_profiler:
toolbar: true
intercept_redirects: false
app_dev/php doesn't have any IP restrictions, it runs AppKernel with dev environment. Also, AppKernel has the:
$bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
The main problem could be the HTML, but it has both opening and closing tags. I even tried to remove all the HTML and just leave it with a few HTML and body tags, no luck.
Is there anything else I could try? Maybe some files could be missing? How can I check it? This is not a fresh installed version of Symfony.
Make sure you can tick all bullets in this checklist:
- You are using the dev mode by accessing the page via app_dev.php (True for you)
The toolbar inserts itself in pages by looking for a terminating </body> tag on your generated page. If you don't have a </body> tag in your page the toolbar will not appear(as in the above answer). Example twig file as a reference:
The line {% extends '::base.html.twig' %} will extend app/Resources/views/base.html.twig which injects default <body>...</body> into your custom twig files.
{% extends '::base.html.twig' %}
{% block body %}
Hello!
{% endblock %}
You have enabled the profiler in AppKernel.php
public function registerBundles(){
$bundles = ...
if (in_array($this->getEnvironment(), array('dev', 'test'))) {
$bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
...
}
return $bundles;
}
You have javascript enabled.
Thoroughly Check recently added bundles(specially custom ones). Because Cases like this can cause the problem.
Double-check that your <body> tag has a closing </body> tag. In my experience, when the toolbar suddenly disappears it's because the closing body tag is missing due to malformed HTML, or because a controller is returning a Response object with just plain text content.
I had this issue with a large(ish) application where the toolbar wasn't being shown on memory heavy pages. Turns out that my php memory limit was being exhausted. I set the memory_limit in my php.ini file to something that would be adequate and that sorted it.
if you set the environment as dev it should display debug toolbar at the bottom
edit web/app.php as following;
$kernel = new AppKernel('dev', true);
I recently got an old project in SF3.4 and in my case the debug toolbar didn't show up because of the following keys in config.yml file
framework:
[...]
profiler:
collect: false
I commented on those 2 lines and it works again.
